在八十年代以前,我国对远红外线技术的推广,还处于比较幼稚的阶段。就辐射涂料而育,多是单纯追求辐射率,即认为辐射率越高,辐射强度越大,就越好。因而当时大部分推广者与元件制造厂都认为涂料越黑、越粗糙,越接近黑体,其辐射效果就越好,就会使被烘物吸收得越好,能使能量的利用率达到最高。通过六年来的实践和理论研究证明,用远红外线加热,并不完全是辐射涂料越黑、越粗糖越好。 Before the 1980s, the promotion of far-infrared technology in our country was still at a naive stage. Radiation coatings and education, mostly pure pursuit of emissivity, that is, the higher the emissivity, the greater the radiation intensity, the better. Therefore, most of the promoters and component manufacturers at that time thought that the darker and rougher the paint, the closer the blackbody is. The better the radiation effect is, the better the absorbed material will be, and the highest utilization of energy will be achieved. After six years of practice and theoretical studies have shown that with far-infrared heating, radiation is not entirely blacker, the more the better the better.
